Costco has recently transitioned its Kirkland Signature diaper production from Kimberly-Clark, the makers of Huggies, to First Quality, known for producing Cuties diapers. This change has raised concerns among parents regarding potential differences in quality and fit.

I haven’t used the new First Quality-Kirkland diapers yet, so I can’t provide a personal comparison. But I definitely would have been blindsided if my sister hadn’t told me!

Early feedback from parents suggests that the new Kirkland diapers may not be living up to the previous version’s standards. Some users report that the new diapers feel thinner, sag more when wet, and are less absorbent—leading to more frequent leaks, especially overnight. Others have noted changes in fit, with some babies experiencing more blowouts or discomfort due to a looser waistband. Since Cuties diapers are often compared to lower-cost alternatives like Target’s Up & Up or Amazon’s Mama Bear, parents who relied on Kirkland as a budget-friendly Huggies alternative may find themselves searching for a new option.

​It appears that the recent supplier change for Kirkland Signature diapers stems from Kimberly-Clark’s strategic decision to discontinue private-label manufacturing, including their long-standing partnership with Costco, to focus on their own premium brands.

Given my reliance on the previous Kirkland diapers over the past year, I believe Costco should proactively inform customers about this change. Notifying parents through website disclaimers or in-store signage would prevent unexpected surprises, such as nighttime leaks or inconvenient diaper failures during outings. Costco plays a vital role for families, especially those with young children, and transparent communication is essential to maintain trust and ensure preparedness for any differences in diaper performance.
